Membrane structure sunshade The flexibility of membrane structure makes it bear load in a favorable form under any load. Of course, the layout and shape of the structure should be designed and adjusted according to the load conditions. The design shall ensure that the membrane surface works in coordination with its auxiliary structure, so as to avoid the concentration of force on the membrane surface or auxiliary structure to reach the critical value of structural damage. The flexibility of the tension structure enables it to produce large displacement without permanent deformation. The elastic properties and prestress level of membrane materials determine the deformation and response of membrane structures. The flexibility of adapting to nature can inspire people's architectural design inspiration. Measure the geometry of the supporting structure and connecting nodes and compare with the design value, and make necessary corrections to the form finding results; Cutting design shall be carried out according to the modified shape, and the film surface shall be processed; If the membrane surface has been fabricated before the completion of the supporting structure, the deviation shall be corrected by other schemes such as changing the specifications of the connecting pieces; Fold and pack the processed film products according to the requirements of the construction organization design, and mark them; Transport to the installation site; Clean the site and pave protective materials on the ground; Explain the process and division of labor to workers; Unfold the membrane surface and carry out preparations such as drilling holes on the membrane surface, threading steel cables, installing membrane corner gusset plates or membrane splints; Bind rope net on the supporting structure to temporarily support the unfolded membrane surface; After the preparations are completed, the hoisting machinery shall be in place, hoisted and temporarily fixed at the diagonal point; Local tensioning adjustment shall be carried out for the corners and wrinkled areas, and finally the membrane surface and nodes shall be fixed; Complete the installation of rainwater system and waterproof cover; At the same time of organizing the acceptance of components, the membrane deployment platform shall be set up according to the site conditions and construction scheme, and the safety net shall be installed. For large tensioned membrane structures, meteorological information during installation shall be collected. During installation, pay close attention to the wind direction and wind speed to prevent the membrane body from shaking. Stop construction in time in strong wind or heavy rain, and take corresponding safety protection measures
